Users will pay for access to create articles. Each article will store information pertaining to a particular topic--like a profile for that topic--all of which will be editable via a CCK.
I would like users to be able to purchase credits that will allow them access to create a certain number of articles. For example, if they purchase 2 credits they can create two articles, one for each of their automobiles. Each article will have a QR-code tied to the URL, so the user needs to be assigned to a specific article. And once that article is chosen, other users should not be able to purchase that article id. This is difficult to explain.
Is there a way to accomplish this in CB. There will be 100,000 or more articles, so I don't want to set up a separate subscription for every article. It would be much better if I could grant permission to edit and/or create one article.
Thanks
